The right decision ;-)

This place is just fine. If we find out that it is a bug we still can  
create one ...

Looking at this I have got one question: Are the system bundle  
(org.eclipse.osgi) and the framework extension fragment  
(org.eclipse.equinox.weaving.hook) colocated, i.e. in the same  
directory? That is neccessary for Equinox to recognize the framework  
extension (see http://wiki.eclipse.org/index.php/Adaptor_Hooks for  
details) => Equinox Aspects will not work if the both bundles are not  
colocated.
